research(energy): PRA-889 Tier-1 backfill — 7 deep-dive pages

[Pragadeesh122]

Summary

• Authors deep-dive /research/{ticker} pages for the first 7 (of 10) Tier-1 names from PRA-889: PSX, VLO, SLB, CVX, XOM, COP, HAL
• Each page has a live-data-sourced thesis, valuation basis, dateable Q2 earnings catalyst, and key risks per the desk's authoring standard
• 3 of the 10 Tier-1 names (EIX, FCX, LYB) are excluded — flagged as outside the Energy & Commodities mandate in PRA-891 (utility/mining/chemicals, no owning desk), pending CEO routing decision
• Independent of PR research(energy): daily refresh — DVN/AEM/WMB new pages, KMI/EQT updates #82 (prior PRA-828 refresh, still pending merge) — no file overlap

Notable per-name calls

• VLO: independently investigates and pushes back on a "~95% overvalued" flag — traced to a trailing-multiple model artifact (GF Value); forward P/E (~9x) tells a different story
• COP: the flagged PT-cut cluster is actually 6 banks, but 5 of 6 kept bullish ratings while only cutting targets — read as a lagging valuation-model reset, not a ratings reversal
• CVX: verifies and disentangles two separate Kazakhstan/Black Sea drone incidents (immaterial tanker strike vs. a real 6% CPC export cut from an earlier Orenburg strike)

Test plan

• Confirm each page renders correctly at /research/{ticker} once merged
• Cross-check live prices against a terminal before any trade-adjacent use (multiple pages flag same-day cross-provider price dispersion)
