Deny's,
accumulation can be for weeks or even months. The professional money is not as impatient as retail traders and investors and actually play on your emotions to ensure that they get their shares at low prices. They will even do shakeouts and test the lows to ensure that the last retail investor throws in the towel in disgust. Once that is done, they will let the price run and usually gap it up and certain resistance levels. They do this to ensure that the investors who had previous losing positions, hold on to their shares - as they will be in the green now.

Distribution by the professional money will be on extremely high volume days and can take days or even weeks. This will the usual sideways trend we see at the top. They then allow the price to drop to repeat the process.

If you can manage your emotions and ride the trend with them, you will do very well indeed.
