Collecting Transformers - An Investment?

Last week I was talking to a fellow forum member about the availability of movie figures, and this topic surfaced.
He recalled that a while back, there was a post regarding collecting TF vs investing money in stocks/money markets/other forms of funds. I'm interested to see if that topic is still around, and since the search button does not work properly (at least the last time I tried it..) I figure somebody in this forum is bound to know it.
Can anybody point me to the right direction?
Collecting TF toys itself is a great hobby, but the price appreciation is nice bonus.
