Carnegie's chart reads almost like a business plan. The 乙 year stem is an Indirect Wealth (偏財) star — wealth won through ventures and deals rather than wages — and the 丁 month stem is Seven Killings (七殺), the star of pressure and competition. The 酉 day branch is a Companion (比肩), giving the Metal Day Master a root of its own; the engine notes that he gains the day branch, which is what keeps the chart balanced.

The 亥 month branch carries Hurting Officer (傷官), the star of invention and breaking with convention, and the 未 year branch carries Indirect Resource (偏印), unconventional learning — fitting for a bobbin boy who educated himself on the job as a telegrapher. The clash between the 乙 year stem and the 辛 Day Master sets his Wealth star directly against him: a sign of wealth gained through struggle, and in his case largely given away in the end.

Symbolically, this is a Metal Day Master who made his name in steel. The Gyeongjin (庚辰) cycle placed 庚 Metal — his own element — on the stem, in the decade he sold Carnegie Steel to J.P. Morgan.
