Coukd you please clarify section 3 for me?
1, thanks for bringing this up. It is a very strange case but I think the Google (and mainstream stock quote) reports are wrong.
I had a China based economics expert review this and they say local stock data shows no sharp move (or fall) in the stock price.
I think he's right (besides the fact that he's a known expert) because (1) Shenzhen only allows 10% max daily moves while Google shows ~30% drop in a day, (2) the Q1 results are quite strong so it does not fit or explain a price drop and (3) I cannot find any other negative information or stories that would explain a drop.
I believe there was a 3:1 stock split (confidence level 80%) at the same time that the earnings came out, which unadjusted would show like this:
The adjusted numbers show that the stock actually rose a good deal:
The reason for the split may have been to make the stock cheaper to buy per unit to facilitate the newly created employee stock ownership program, (conf. lev. 65%).
Google may not have recognized the split action, (c.l. 50%), yet but I have no idea why they show 18, not 33, before the split.
