摘要

实物期权理论(“ROT”)认为企业应该是实物资产和实物期权的结合。国内股票研究分析师似乎没有评估应用ROT的公司。在审查了2020年12月31日至2021年4月30日期间对巴西上市发电公司的344份(估计总数为368份)股票研究报告或分析后,我们发现只应用了贴现现金流(“DCF”)技术。对ROT只字未提。为了估计潜在估值错误的程度,我们使用Black-Scholes方法对这15家公司在这一时期公开发布的增长计划进行定价,并将结果与分析师预测的每家公司的股票价值上涨幅度进行比较。我们的研究结果表明,由于未能应用ROT,当地分析师忽略了这些公司的相当大的内在价值。潜在的解释范围从行为偏见到IBOVESPA的低权力部门代表性。

Real Options in the Brazilian Power Generation Sector: Are Domestic Equity Research Analysts Blind-Sighted or Is It Just a Temporary Glitch?
The Real Options theory (“ROT”) states firms should be approached as a combination of real assets and real options. Domestic equity research analysts do not seem to evaluate companies applying ROT. After reviewing 344 (from a total estimated 368) equity research reports or analyses on Brazilian listed power generation companies produced between December 31, 2020, and April 30, 2021, we find only discounted cash flow (“DCF”) techniques are applied. No single mention to ROT is made. To estimate the magnitude of potential misvaluations, we use the Black-Scholes method to price the growth plans made publicly available by each of those 15 companies in that period and compare the outcome with the analysts’ forecasted equity value upside per company. Our results suggest local analysts have ignored a sizeable intrinsic value to those companies by failing to apply ROT. Potential explanations range from behavioral biases to low power sector representativeness at IBOVESPA.
