In this paper, we present empirical results from the Swedish equity market when testingdifferent strategies aiming at enhancing the performance of a momentum strategy, over a timeperiod from 2000 to 2021. Similar to research conducted on other markets, we find theexistence of a momentum premium on the Swedish equity market, but with a return that is fattailed and negatively skewed. We show that forming momentum portfolios by ranking stockson the residual return instead of total return increases the Sharpe ratio and reduces the excesskurtosis and skewness. Furthermore, managing volatility by scaling the exposure to the twomomentum styles increases performance of both, but most notably for the traditionalmomentum factor. Assessing the high average returns in relation to the high turnover of theportfolios, we find it likely for the net return after accounting for transaction costs to bestatistically significant based on research on factor strategies and limits to arbitrage. / Denna uppsats undersöker ett antal momentumstrategier på den svenska aktiemarknaden övertidsperioden åren 2000 till 2021. I linje med tidigare forskning visar vi på enmomentumeffekt, där aktier som presterat bättre (sämre) relativt andra under föregående årtenderar att prestera bättre (sämre) även i kommande månader. Vi visar attmomentumportföljer som rankar aktier utifrån dess idiosynkratiska avkastning underföregående tidsperiod förbättrar den riskjusterade avkastningen i jämförelse med dentraditionella momentumfaktorn. Förbättring visas även i en ökad symmetri med en minskadsannolikhet för extrema negativa utfall, ofta benämnt som ”tail risk” i sammanhanget. Vidareundersöks riskstrategier som låter exponeringen mot faktorportföljerna variera baserat påhistorisk volatilitet och resultatet visar på en förbättring, främst för den traditionellamomentumfaktorn. Baserat på portföljernas höga medelavkastning över tidsperioden och denmånatliga omsättningen finner vi det troligt att den positiva avkastningen förblir statistisktsignifikant efter hänsyn tagits till transaktionskostnader.

Volatility-managed portfolios offer mixed returns in an international setting based on ex-ante information. The results of this paper further strengthen the theory that the variability of excess returns from volatility-management are more dependent on underlying investor strategy rather than differences of global markets. We find that momentum strategies, as measured by the winners-minus-losers, are universally (except Japan) benefitted from volatility-management with an excess return between 6.96% and 14.28% annually across different regions/cross-sections garnered by the managed portfolio controlled against the Fama and French (2015) five-factor model. Value and profitability factors show mixed results with the beneficial performance in about half of the examined regions respectively. We prove that these relationships are robust through periods of market-wide crashes (Dotcom-bubble and financial crises of 2007/2008), tighter leverage constraints (≤1, ≤1.5) show however that the excess returns are dampened, concluding that access to leverage is a fundamental aspect of employing volatility-management to most portfolios. The results of this research paper expand previous literature of volatility-management by broadening the strategy to global markets.
