On solar, I have said the rally would slow, or stop, when they start becoming profitable, maybe Q4 (rept Q1) or a Q or so later. I have held on.
They are all up again today in PM trading.
TAN was up last week largely on SCTY, and for the life of me, I can't understand the underlying financial justifications.
On VIPS. I was in it at 28 or so, I mostly lost confidence bcse of the volatility. Since I got out, I loaded up on YY, SFUN, FENG, DANG, maybe another. But the VIPS move has been amazing. on a YTD chart, it beats all the above.
