Alot of people have fallen prey to sensationalist headlines for Video Game stocks at this past E3, but mostly so when it comes to Nintendo stock.

E3 2012 occurred on June 5th to 7th of this year, and from June 6th to 13th, stock commentators and analysts have been blaming declines in Nintendo stock on Nintendo's presentation. However, their analysis could not be more wrong.

Indeed, it had been a few weeks that Nintendo's stock had been declining, and moreover, the ups and downs are only part of its regular cycle of buying and selling. As a matter of fact, after the last article on June 13th, Nintendo's stock has been on the rise, going to show even more how the E3 event had little effect on the stock.

Similarly, if we look at the lifetime trend of Nintendo stock, despite all the E3's during which Nintendo was d0med, the stocks never reflected such a dome.

This phenomenon also happens for other video game manufacturers:

Capcom:

THQ

And so on and so forth.

The truth is, many other factors are much more important in the long-term and short term fluctuations of video game stocks.

Thanks for sharing your thoughts

I'd like to see Ubisoft, if E3 actually effected the stock market of all companies Ubisoft should have the biggest increase.

Both Microsoft and Sony have been doing better during the past 3-4 days than directly before or after E3.

E3 isn't "that" important to the stock value of these companies that are not exclusively game companies, a little bit more important to the exlusive game companies though, but not much. Don't think it really affected the Ninty stock directly.

As if most investors watched E3 or had any idea about gaming...

I don't think investors really care about E3, and most, if not all, devs had a stock fall post-E3, due to other factors outside of the gaming industry.

Go to google finance and search for ubisoft, then say "5d" in the time filter. In the meantime, here is the lifetime curve:
