Research firm American Technology has maintained its “buy” rating on Apple stock along with its previous $101 price target.

The research firm believes that the iPod nano is losing its market grasp and requires a refresh of storage capacities or a drop in prices to re-ignite interest. The firm expects capacities of 4GB and 8GB for future nanos.

“We anticipate these new Nanos will become available in the September quarter and become top sellers, particularly if AAPL keeps its price points low at $199 and $249,” said a spokesman for the research firm.
