The technology world is abuzz with headlines today! Yahoo Inc (YHOO) may be acquired by Microsoft (MSFT), which sent shares soaring, while Google Inc (GOOG) missed earnings expectations and plummeted.

Before looking at the charts, let’s look at the headlines:

From Yahoo Finance: Microsoft makes $44.6 Billion Bid for Yahoo

Yahoo’s stock, like the up arrow in their logo shown here, is headed up, up, up (this morning at least).

Also, from Fortune Magazine this morning: “Putting Yahoo and Microsoft Together… Some Pieces Won’t Fit.”

As if this wasn’t enough to keep the technology world buzzing this morning, search engine giant Google announced yesterday that it missed earnings, but would have hit them if employee stock bonuses/options were not included.

From The Street.com: “Google, Microsoft, and Yahoo… Oh, My!”

Also from Fortune.com: “Google Misplaces $72 Billion” Oops! That’s what the author estimates was the loss from the earnings miss and the decline from the all time price high. An excerpt:

“Fortune’s Philip Elmer-DeWitt notes that Google stock has now dropped more than 230 points from its November high of $747 a share – wiping out more than $72 billion in market value. That’s more than half again as much as Microsoft (MSFT) is offering for Yahoo (YHOO), for instance.”

That really puts things into perspective, or at least tries to.

Now that you have the headlines, let’s glance at the charts:

Microsoft (MSFT):

Oops. Investors were not pleased. This is the traditional reaction, in that the offering company takes a hit to their stock price when the news is announced while the company being acquired experiences an expected stock pop.

Like what happened in Yahoo (YHOO):

Wow is the word of the day. The day is not finished yet, and already over 365 million shares have traded today. That is some massive volume! Notice the slight volume pick-up on the days prior to the announcement. Did someone know this was going to happen? I’ll look at the options later to see if there were clues.

Yahoo’s share price has appreciated 47% or just over $9.00 as of 2:30 EST.

Unfortunately, the news was not all good today. Google investors woke up to a massive decline which was exacerbated to the downside as the day continued:

As of 2:30 EST, Google’s share price has taken a 7.86% decline, which is $44.36.

For trivia’s sake, the 14 period (day) Average True Range (ATR) for Google is actually near $28, meaning that in one day, a $28 price fluctuation up or down would be normal.

With wild swings up and down like this in the stock charts, is anyone safe?
