Just a side note in the portfolio, I unloaded the last 100 shares of a company that was relatively illiquid (market cap under $20 million). The algorithmic order I set was placed in early October and the execution finished today.
The whole trade (in and out) ended up losing the portfolio less than 2%, but obviously the story after the investment was made changed which triggered my exit order. Getting in and out of illiquid stocks is a real pain, and unless if the potential risk-reward ratio is disproportionate, such transactions should be valued explicitly with a discount acknowledging the lack of liquidity.
Throughout my history my dabbling in illiquid stocks has been less than spectacular – my sweet spot of investing has tended to be small cap stocks ($100M-$1B capitalization) instead of microcaps.
