Not sure when your baseline starts but many sectorial stocks (property, bank, commodities, infrastructure) moved up a lot since a year ago, but many stocks are still way off the last highs.

On Midas, the stock not only went up cos of dual listing.  The company has set its financing in order for new production lines (yes, the recent placement was part of the plan), it won contract after contract and the order books are full on existing capacity for the next few years, and it continue to plan capacity to anticipated growth being in an oligopoly market for specialty rail cars in China.

No one can assure that Midas share price can only rise.  Short term play is always at mercy of global market sentiments and BB actions. But on the same breath, to state that price will come down below 68 cents seems casual.  Midas is not building railway projects (network).  Like another forumer mention, the Chinese rail network is part of a nationalised infrastructure plan - this is not subjected to credit control unlike for luxury housing and SMEs.  You can readily read about Chinese rail plans in the Internet - it is expanding at an unprecedented amazing pace and China know it needs this to hold the long term intra-China economy in a coherent manner.
