Yes, I do too. However what I can't fathom is the number of shares on the market and how it changes (or potentially doesn't change now).
Take Sancho as an example. He is worth c.£13.50 now. Let's say there are 50,000 shares of him held across all traders. You can no longer sell back to FI through Instant Sell.
When he is 34 and approaching retirement, there are still going to be at least 50,000 shares of him held across all traders (that's assuming no one has let their shares expire and he has not gone any higher than £13.50). But as he's approaching retirement, his price is now £2.
That means some people are going to be holding Sancho above £13? That is a humongous loss.
The answer might lie in the full order books and I haven't fully got my head round how they will work. However, I don't think full order books will change number of shares on the market. The only way that will happen is by buying shares from FI, which means the number of shares on the market only ever going one way...
