I did not do SNDK yesterday because it opened close to the top of the box ($58.5) but could not take that level out all day, despite the Naz continuing its advance yesterday. To me it was a sign that there is a lot of supply at $58.50. Maybe with the premarket open above that level, that supply will disappear. I traded it earlier between $54 and $57 the day before. Because I am far from "sure" on that support (and the current flash ebullience), I sold the SSTI with 6% profits, which will be ample to cover a potential loss if $58.5 is "given back." (g).
