Tangible V/S Intangible Assets

Value vs. Growth Investing. Very interesting trend analysis in the composition of the stock market between the value of companies with tangible vs. intangible assets. Over the past 5 decades, the value placed on tangible assets is inverse to intangibles today. I don’t expect this trend to reverse back to tangibles; however, there is a justifiable basis that investors will start analyzing the value of the tangible assets that are overlooked that contribute to the value of the intangible assets. A key factor will be cash flow generation and how much the intangible asset relies on it. Any ideas?
