Financial Dictionary: Glide Path

In reading more of the business sections and financial literature, I’m continually disappointed by the amount of assumed knowledge in the writing. To be expected, probably, but I want to start making the effort to learn more of the vocabulary, as well as the principles behind good investments. Starting with:

Glide path (n.): the rate at which retirement funds change their asset allocations (mix between stocks and fixed) over time
In a sentence: Much of the controversy over target-date retirement funds is due to the lack of consensus around the correct glide path for these funds, and what the right percentage of equity one should have on the day of one’s retirement.
