Well it's not likely to be an increase in customer service and less fast track etc is it?
Think I might leave this debate alone now.
Investment revenue is great for expanding a business, but when you already have capital investors there is only one reason to float.
Let's take a football club as a simple example. Those who buy the clubs outright, like good old Randy Lerner of my beloved Aston Villa, took the club off the Stock Market. Why? Because he didn't need the money, and it bleeds a club of revenue.
On the other hand, let's take a quick peek at the giant Man U. They're servicing a lot of debt, with owners having to flog a ton of their assets, and went off to float the club to raise revenue.
If you have the capital, you don't need to float the company to grow. If you float the company, you're always at the behest of expectant shareholders and dividend yields, and if someone makes a royal cock up of it, or the market crashes, all of a sudden your company is worth a shed load less for no logical reason.
The stock market is a big game, full of gamblers, and it's very exciting, and I'd never put my own money in it, because for every winner there are a heck of a lot of losers.
