1. The addition of the prefix over- makes both verbs transitive (i.e. take an object) and therefore they do not entirely correspond to the grammatical functions of lay and lie. The past tense and past participle of overlay is overlaid, and of overlie are (past) overlay and (participle) overlain. The primary meaning of overlay is 'to cover (one thing) with another' as in overlaying a surface with a coating or in smothering a child by lying on top of it (overlie is also used in this meaning and is somewhat more common). Both words are used in geology to mean '(of a stratum) to lie over (another)'.

2. Overlay (with stress on the first syllable) is also a noun, whereas overlie is only a verb.

1. Transparent or semitransparent covering used to protect artwork or photography, or as a means to surprint instructions, corrections, changes, copy variations, or comments on art, photography, text, or an existing design. For example, color-breaking instructions for the photoengraver are usually marked on an overlay that is pasted on an original black-and-white piece of artwork. Since these instructions are not written directly on an original, the proper specifications are communicated without touching the original design. In addition, the original copy is protected from damage or smearing. Cellulose acetate or tracing tissue are most commonly used for overlay purposes.

A management style that harmonizes an investor's separately managed accounts, preventing the formation of inefficiencies. Overlay management uses software to track an investor's combined position from the separate accounts. Any possible portfolio adjustments will be analyzed by the overlay system, which ensures the overall portfolio will remain in balance and prevent any inefficient transactions from occurring.

Investopedia Says:
When an investor has separately managed portfolios, that investor is placing assets under the control of different managers. This can cause inefficiencies if the managers begin making transactions that either increase the risk of the overall portfolio, have negative tax effects, or unbalance the investor's positions.

For example, if one of the separately managed account traders purchases an asset and another trader sells it, the investor will be left with a neutral position and two transaction fees. Overlay management seeks to improve the communication between the separate managers, allowing for increases in transaction efficiency.
