Japanese shorts are not only less Crowded but also less Squeezable with an average Squeeze score of 34.61 versus the worldwide average of 39.93. Over the last thirty days Japanese shorts were down -1.24% on average versus a positive +0.05% return for worldwide shorts. But Squeezability has a recency bias with short sellers feeling shorter-term profits & losses more stringently than longer-term profits & losses. Japanese shorts are down -1.85% over the last seven days versus the worldwide average of -4.14%. Worldwide ex-Japan are getting relatively more squeezable due to their recent mark-to-market losses.

We measure Squeezability not only by looking at a securities Squeeze score but also the Crowded\Squeeze score spread. A Squeeze score over 70 and\or a spread of +20 tells us that a security has a higher-than-average squeezability factor. The most Squeezable Japanese stocks with over $25 million of short interest are:

While a higher Squeeze score does not guarantee a slew of buy-to-covers hitting the tape it does tell us that short sellers will probably not be looking to increase their exposure in a particular stock and may look for attractive exit points as they present themselves. A long investor should take this into consideration when choosing between stocks – better to be long in an unattractive short trade than an attractive one. And a short seller needs to raise these stocks higher on their radar as they never want to be the last short seller to exit their trade as stock prices continue to rise.
