Well, apparently not.
Why would you post such a statement AFTER the price increased the pre-split equivalent of about $10.50 and set a new 52-week high on the first day of post-split trading.
The ship on the predicted sell-off has sailed. Even if it pulls back tomorrow, that will be after a big up day, so it will probably end up flat to slightly up on a net basis.
I'm not sure why people think that splits, per se, result in a decline in stock price. I guess they cite Google and MasterCard, so yeah, two companies go down so, therefore, all companies will go down.
If share price always declined after a split, then no company would ever split their stock.
