LOL!!!Accumulation is not measured at the individual level. Have to use technical analysis, then you introduce accumulation/distribution, and you get a measurement. It can be traced several months or years.
In the case of DOLV, accumulation shows a steady increase from May (about 2.2 millions) to October (about 140 millions).
Add to that that DOLV is in REGSHO, the short must be enormous.
Or....you could sell for a profit, as in your example, and when you buy back, you just buy more with your profit, thus accumulating more shares.....GO DOLAT dba JZMY888
