When Facebook's acquisition of Instagram happened, which took just a weekend to happen, it was valued at over $1 billion. This was mainly because the social network's stock prices were quite high pre-IPO, and the deal with Instagram included $300 million in cash, and 22,999,412 shares of Facebook, valued at $38 a piece.

We've seen how the Facebook shares have tanked, yes I've used the word again, and continue to do so. This has had a ripple effect on Instagram, with the first trade of Facebook coming in at a now incredible $42.05, with the same shares now trading at a paltry $19.05 on Friday. This is a huge 41.88% difference between the first trade, and Friday's pricing.

This means if we include the $300 million in cash Instagram will take, as well as the near-23 million shares, the deal is sitting at just $738.1 million. As you can see, $738 million compared to over $1 billion is quite the difference in just a couple of months.

Did you buy shares in Facebook, if so, have you sold them yet, or are you holding on for a glimmer of hope?
