The Dow created a new trend channel for price to follow recently. The bottom in the first week of February signaled a change of character as far as momentum is concerned.
The end of Feb. the first of March price regained the 25 and 50 day MA's which signals a return of modest optimism. As long as price continues to hold this channel we are still in an upmove. If price breaks below this channel then we have turned bearish.
As you can see from the chart we can still move a long way to the upside from here although at a slower pace than we had in 2009.
