NYSE Euronext (NYX)

[metropick]

I also bought in initially at 104.5.

I recommend you buy incrementally and not buy all at once. That will help you average down. NYX is a great stock, make no mistake! I am buying more today if it gets <100.

Stocks fluctuate, and they dip for seemingly no good reason at points. NYX is a growth stock, and growth company share prices fluctuate even more so than value stocks. I think NYX is a long term play that will reap benefits for at least the next two years.

Sell now, and you take your loss. Sell when it gets up to 108, then you'll have a a small gain and pay short term capital gains taxes (~30%). Wait to sell, and average down your position and you will be rewarded with a nice return and long term capital gains tax (~15%)

It also helps to keep reminding yourself why you bought the stock to begin with.
