The bitcoinstockexchanges is rather limited at the moment unless you only want one that more or less only trades there own stock.
 
Cryptostocks have around 70 stocks but there is many scams and halfscams among them so you really have to be very carefull with what you buy there and CS is hardly doing anything to stop scams from listing there, they only seems interested in getting the 1 btc fee(and getting fees on trades) for listing stocks and probably does zero checkup on the listings.

Havelock have 21 stocks and people say there better quality in general on the listings there and from the little i looked at them it may be correct but it also seems like there way worse than what btc-tc/ltcglobal & Bitfunder was before.

Crypto-Trade have 4 of there own stocks and some lemon/avocado farmer and AMC, AMC illeagally sold off/dumped "ukyo/ukyo loan investors/weexchange balanceholders" shares without ukyo's permission and then tradestopped the share so the fact that they allowed that hardly makes CT look any better than CS,

Then you have Mpex where you can buy 4 of there own stocks if you first pay them 30 btc to be allowed to trade there,

Mcxnow have there own share at there exchange,

Picostocs have a few stocks but they look even worse than cryptostocks, only 4 out of 39+ listings is till there.
