One way of interpreting a portfolio PE is by comparing the same with the benchmark PE.

If a portfolio PE is higher than the benchmark PE, then one can interpret the portfolio as being overvalued when compared to the benchmark

One can also compare the current PE of the portfolio with its historical value to understand whether the portfolio is undervalued or overvalued.

If a portfolio has more companies growing at a fast pace, then PE ratio of the portfolio can be high as these companies usually are expensive compared to the rest of the market. If the portfolio companies have had weak total earnings, the total PE ratio could be inflated because of low denominator. Hence one has to closely inspect the portfolio companies before drawing any conclusion about portfolio PE ratio.
