These Are The 10 Most Crowded Long And Short Trades According To UBS

In this market where fundamentals long ago ceased to matter, and where positioning remains one of the few remaining sources of alpha, investors have been focusing on lists showing the most over and under-owned stocks. However, contrary to the narrative that the most heavily owned stocks outperform the most shorted, or underowned ones, and vice versa, recently BofA calculated that for the third year in a row, "the Top 10 most overbought stocks have trailed the S&P for each of the past three years, while the Top 10 "most neglected" stocks outperformed the S&P on average by 11.6%."

This is what BofA's quant team found:

As flows from active to passive funds have accelerated, one strategy that has worked unusually well for the last several years is a simple positioning trade of selling the 10 most overweight stocks and buying the 10 most underweight stocks by active managers. This single trade has yielded over 16ppt of alpha year-to-date. And implied derisking/ outflows on Brexit alone have been fierce, with the same strategy generating 5.2ppt of alpha just since last Thursday’s close. Even if Brexit’s impact on funds is limited from here, we believe that crowded stocks will likely continue to underperform neglected stocks: a whopping two-thirds of US large cap AUM still resides in active funds - there is likely a lot more to go in the rotation from active to passive.


As such, a useful trading framework, would be to look at the Top 10 most crowded trades of active managers - on either side of the ledger - and to short the 10 most overweight, while going long the 10 most underweight stocks.

Conveniently UBS has updated its list of the Top 10 most crowded trades, revealing "where are the largest active positions." How does UBS  measure the most active positions?

Using the institutional ownership data provided by FactSet, we form an active trading portfolio by aggregating positions across global active managers. Essentially, we sum up all the holdings in dollar value across all the active managers and calculate the weights of stocks in this active trading portfolio. We then compare this weight with the relevant equity index benchmark to form the active weight.

So, without further ado, here according to UBS are the Top 10 most crowded long and short trades, and not surprisingly, it's all tech among the top 5 longs, which include Google, Alibaba, Amazon (a jump from 8th spot as of the last ranking), Facebook and Visa (with AAPL sliding into 6th spot), while on the short side one name stands out: Tesla in the perennial top slot, which may explain why no matter how bad the news, even the smallest glimmer of hope, whether a tweet from Elon Musk or an upgrade, prompts a sharp squeeze, like today for example.

Based on UBS data, this is how these two baskets have performed on a YTD basis:

Finally for those wondering, here is a breakdown of how levered hedge funds are as mid-July courtesy of JPM Pribe Brokerage. It will probably not come as a surprise that every single category has increased its leverage on a 3M, 6M and 12M basis.
