In the past 6 months, everytime when the hitted the 30 mark, the stock price was either AT or CLOSE to its trough/bottom.
In my opinion, the has shown us that the 30 mark became a great support line and an excellent leading indicator. Whenever it reached the 30 mark, it has bounced off and allowed the stock price to reach new highs.
According to the OBV and Accum/Dist Chart, the accumulation of Yahoo stocks at current prices are fairly stable. I would like to see the Accum/Dist to move a little higher, for it to indicate an even more move.
Furthermore, on the chart, the recent reversal where the 12 day has crossed over the 26 day is another sign for the near future.
