    Hedge Fund Performance and Persistence in Bull and Bear Markets DANIEL P.J. CAPOCCI University of Liege - Economics, Business Administration and Social Sciences A. CORHAY University of Liege - Department of Financial Management; University of Maastricht (formerly University of Limburg) - Department of Finance GEORGES HUBNER University of Liege - Economics, Business Administration and Social Sciences ------------------------------------------------------------------------ -------- Abstract: This paper tests the performance of 2894 hedge funds in a time period that encompasses unambiguously bullish and bearish trends whose pivot is commonly set at March 2000. Our database proves to be fairly trustable with respect to the most important biases in hedge funds studies, despite the high attrition rate of funds observed in the down market. We apply an original ten-factor composite performance model that achieves very high significance levels. The analysis of performance indicates that most hedge funds significantly out-performed the market during the whole test period, mostly thanks to the bullish sub-period. In contrast, no significant under-performance of individual hedge funds strategies is observed when markets headed south. The analysis of persistence yields very similar results, with most of the predictability being found among middle performers during the bullish period. However, the Market Neutral strategy represents a remarkable exception, as abnormal performance is sustained throughout and significant persistence can be found between the 20% and 69% best performers in this category, probably thanks to an extreme adaptability and a very active investment behavior.Hedge fund, hedge funds, carhart, capocci, hubner, performance, persistence, decile analysis

    Tocilizumab in patients admitted to hospital with COVID-19 (RECOVERY): a randomised, controlled, open-label, platform trial

    Background: In this study, we aimed to evaluate the effects of tocilizumab in adult patients admitted to hospital with COVID-19 with both hypoxia and systemic inflammation. Methods: This randomised, controlled, open-label, platform trial (Randomised Evaluation of COVID-19 Therapy [RECOVERY]), is assessing several possible treatments in patients hospitalised with COVID-19 in the UK. Those trial participants with hypoxia (oxygen saturation <92% on air or requiring oxygen therapy) and evidence of systemic inflammation (C-reactive protein ≥75 mg/L) were eligible for random assignment in a 1:1 ratio to usual standard of care alone versus usual standard of care plus tocilizumab at a dose of 400 mg–800 mg (depending on weight) given intravenously. A second dose could be given 12–24 h later if the patient's condition had not improved. The primary outcome was 28-day mortality, assessed in the intention-to-treat population. The trial is registered with ISRCTN (50189673) and ClinicalTrials.gov (NCT04381936). Findings: Between April 23, 2020, and Jan 24, 2021, 4116 adults of 21 550 patients enrolled into the RECOVERY trial were included in the assessment of tocilizumab, including 3385 (82%) patients receiving systemic corticosteroids. Overall, 621 (31%) of the 2022 patients allocated tocilizumab and 729 (35%) of the 2094 patients allocated to usual care died within 28 days (rate ratio 0·85; 95% CI 0·76–0·94; p=0·0028). Consistent results were seen in all prespecified subgroups of patients, including those receiving systemic corticosteroids. Patients allocated to tocilizumab were more likely to be discharged from hospital within 28 days (57% vs 50%; rate ratio 1·22; 1·12–1·33; p<0·0001). Among those not receiving invasive mechanical ventilation at baseline, patients allocated tocilizumab were less likely to reach the composite endpoint of invasive mechanical ventilation or death (35% vs 42%; risk ratio 0·84; 95% CI 0·77–0·92; p<0·0001). Interpretation: In hospitalised COVID-19 patients with hypoxia and systemic inflammation, tocilizumab improved survival and other clinical outcomes. These benefits were seen regardless of the amount of respiratory support and were additional to the benefits of systemic corticosteroids.

    Convalescent plasma in patients admitted to hospital with COVID-19 (RECOVERY): a randomised controlled, open-label, platform trial

    Background: Many patients with COVID-19 have been treated with plasma containing anti-SARS-CoV-2 antibodies. We aimed to evaluate the safety and efficacy of convalescent plasma therapy in patients admitted to hospital with COVID-19. Methods: This randomised, controlled, open-label, platform trial (Randomised Evaluation of COVID-19 Therapy [RECOVERY]) is assessing several possible treatments in patients hospitalised with COVID-19 in the UK. The trial is underway at 177 NHS hospitals from across the UK. Eligible and consenting patients were randomly assigned (1:1) to receive either usual care alone (usual care group) or usual care plus high-titre convalescent plasma (convalescent plasma group). The primary outcome was 28-day mortality, analysed on an intention-to-treat basis. The trial is registered with ISRCTN, 50189673, and ClinicalTrials.gov, NCT04381936. Findings: Between May 28, 2020, and Jan 15, 2021, 11558 (71%) of 16287 patients enrolled in RECOVERY were eligible to receive convalescent plasma and were assigned to either the convalescent plasma group or the usual care group. There was no significant difference in 28-day mortality between the two groups: 1399 (24%) of 5795 patients in the convalescent plasma group and 1408 (24%) of 5763 patients in the usual care group died within 28 days (rate ratio 1·00, 95% CI 0·93–1·07; p=0·95). The 28-day mortality rate ratio was similar in all prespecified subgroups of patients, including in those patients without detectable SARS-CoV-2 antibodies at randomisation. Allocation to convalescent plasma had no significant effect on the proportion of patients discharged from hospital within 28 days (3832 [66%] patients in the convalescent plasma group vs 3822 [66%] patients in the usual care group; rate ratio 0·99, 95% CI 0·94–1·03; p=0·57). Among those not on invasive mechanical ventilation at randomisation, there was no significant difference in the proportion of patients meeting the composite endpoint of progression to invasive mechanical ventilation or death (1568 [29%] of 5493 patients in the convalescent plasma group vs 1568 [29%] of 5448 patients in the usual care group; rate ratio 0·99, 95% CI 0·93–1·05; p=0·79). Interpretation: In patients hospitalised with COVID-19, high-titre convalescent plasma did not improve survival or other prespecified clinical outcomes.

    Les Fonds alternatifs sont-ils réellement décorrelés des produits d'investissments classiques?

    No full text
    Cette étude a pour objectif d'analyser en profondeur la corrélation qui existe entre les stratégies d'investissement alternatives communément appelées hedge funds et les produits d'investissement classiques. Nous procédons à une analyse en regroupant les fonds par stratégie d'investissement dans des indices composites et en les considérant de façon individuelle. De plus, nous procédons également à une analyse sur différentes sous-périodes afin d'analyser la constance des résultats obtenus. Nos résultats soulignent l'importance d'une dissociation des hedge funds par stratégie d'investissement car les résultats sont spécifiques aux stratégies et au fait que l'on considère les hedge funds en les groupant par stratégie ou de façon individuelle.info:eu-repo/semantics/publishe
